The game is quite unique and very extended. The plot is catching, even if sometimes few stories are a bit long. The graphics is excellent and  all the girls are really cute, not the MC.
Possibly I would have expected much more lesbian scenes, being a world with all women, particularly between Airi and  Momoko,  Momoko and Tomoko , Airi with Kata and Tomoko with Tamika.
I do not understand the Sada character: what does it do in the house?
Despite of thess points, I recommand the game.
